John, > Asssuming DegToRad() just means multiply by pi / 180 ... Well, you may use any calculation in there that you want, as long as it does the job. :-) But yes, thats what the/my DegToRad function does. > ... then the above simplifies to tan(Latitude*pi*pi/720)\2.53627, and > of course pi*pi/720 can be given as a constant. I didn't even think that far. As I said, I'm no math wizz. :-| Regards, Rudy Wieser
